Synthesis of 4-substituted 2H-naphth[1,2-b]-1,4-oxazines, a new class of dopamine agonists
摘要:
A series of tricyclic oxazines, namely, the 4-substituted 2H-naphth[1,2-b]-1,4-oxazines, have been synthesized and assayed for dopamine agonist activity. One of the members of this series, compound (+)VII-15, was found to be a remarkably potent agonist in vivo when tested in the standard 6-hydroxydopamine lesioned rat assay. The absolute configuration of the compound corresponds to that found in the active isomer of apomorphine. Its activity at the alpha 2 receptor (vs. [3H]clonidine) is relatively low. It also failed to stimulate the synthesis of cAMP in the carp retina assay, thus giving the compound a highly selective profile in favor of the D2 receptor.
As part of a project concerned with the synthesis of rigidcongeners of adrenergic drugs, some naphthoxazines, cis and trans isomers of 2,3,4a,5,6,10b‐hexahydro‐4H‐naphth[1,2‐b][1,4]oxazine (1) and cis and trans isomers of its isoster 2,3,4a,5,6,10b‐hexahydro‐1H‐naphth[2,1‐b][1,4]oxazine (2) were prepared. The absoluteconfigurations of these compounds were determined by means of chemical correlation
